Definitions
- the invention relates to a suitable for high axial loads radial roller bearing according to the preamble of forming features of claim 1, and it is particularly advantageous to single-row Kugelrollenlagem imple-sible, for example, as a fixed bearing for the input and output shafts of a motor-vehicle gearbox used.
- the width of these ball rollers between their side surfaces is less than the distance between the radially opposite axial ribs of the raceways formed in the bearing rings, so that the filling of the bearing can be done with the ball rollers in the so-called Axialmontageclar, in which the ball rollers can be axially inserted through the distance between the inner ring and outer ring in the camp. If the center of the ball rollers is then at the level of the track axis, the ball rollers are rotated once vertically and once horizontally by 90 °, so that they can roll with their running surfaces in the raceways of the bearing rings.
- the invention is therefore based on the object to design a radial rolling bearing, in particular single row ball roller bearing, which is suitable in addition to a high radial load capacity for variable axial loads under high operating pressure angles on both sides of the bearing longitudinal axis.
- this object is achieved in a radial roller bearing according to the preamble of claim 1 such that on the one hand the raceways are formed in both bearing rings with an increased depth and width and on the other hand, the ball rollers have a tuned to an operating pressure angle of 20 ° width between their side surfaces ,
- the depth of the raceways in the inside of the outer bearing ring and in the outer side of the inner bearing ring is about 20% of the diameter of the ball base of the ball rollers, while the width of the raceways in the bearing rings is about 80% of the diameter of the ball basic shape of the ball rollers.
- the formation of the raceways of such dimensions is even slightly over the raceway dimensions of conventional deep groove ball bearings and ensures that the ball rollers depending on the radial bearing air even at operating pressure angles up to 25 ° to a high Schmiegungsgrad have their careers and thus the bearing reserves the full radial and axial load capacity even with mixed axial and radial load.
- the radial rolling bearing according to the invention finally has the feature that the width of the ball rollers between their side surfaces about 55% and the distance between the radially opposite axial edges of the raceways is about 60% of the diameter of the ball basic shape of the ball rollers.
- the width of the ball rollers of 55% of their basic shape of the ball represents an optimum in that the ball rollers with this width for a light by the dimensioned with 60% of the ball base distance between the rims of the raceways are mounted.
- the inventively embodied ball roller bearing thus has the advantage over the known from the prior art ball roller bearings, that it now by training with very deep and very wide tracks for the ball rollers in combination with the formation of ball rollers with a wide operating pressure angle matched width now a high radial load capacity is also suitable for variable axial loads under high operating pressure angles on both sides of the bearing longitudinal axis.
- Figure 1 is a side view of an inventively designed ball roller bearing
- Figure 2 shows a cross section through an inventively designed ball roller bearing under axial load
- FIG. 3 shows an enlarged view of one half of the cross section through the ball roller bearing according to the invention designed according to detail X in FIG. 2.
- the width b ⁇ ⁇ of the ball rollers 5 between their side surfaces 6, 7 is, as can be seen from Figure 3, less than the distance a B between the radially opposite axial edges 13, 15 and 14, 16th the raceways 11, 12 in the bearing rings 2, 3, so that the ball rollers 5 are inserted through this distance a B in Axialmontage vide in the radial rolling bearing 1.
- the depth t ⁇ _A, tu of the raceways 11, 12 in the inner side 9 of the outer bearing ring 2 and in the outer side 10 of the inner bearing ring 3 is about 20% of the diameter dK of the ball basic shape of the ball rollers 5, while the Width b ⁇ _ A , b L ⁇ the raceways 11, 12 is about 80% of the diameter d K of the ball basic shape of the ball rollers 5.
